Cassette lift operation
There are two types of cassette lift operation: cassette lift-up and cassette lift-down. The paper stack
surface is lifted up to the pickup position. The lifting plate is lifted down when the pickup operation is
not performed. The lift-up and lift-down operations are described in the following. Both upper and lower
cassettes perform the same operation.
Lift-up operation
The DC controller rotates the cassette lifter motor until the cassette lift-up sensor detects the lifter rack.
Accordingly the lifter moves up and the lifting plate moves up to the pickup position. The lift-up
operation is performed when the product is turned on or when the cassette is installed.
The DC controller determines a cassette lifter motor failure and notifies the formatter when the cassette
lift-up sensor does not detect the lifter rack within a specified period from when the lift-up operation
starts.
Lift-down operation
The paper loaded in the cassette presses against the cassette pickup roller when the lifting plate is in
the pickup position. If this condition is kept for a long time, the paper deformed and a pickup failure
may occur. Therefore, the lifting plate is moved down to release the paper from the pickup roller when
a print operation is not performed.
